fix(debugger): finish PHP Remote Debug: taken port, waiting state, Port field (#1639)

A taken port now says which port is in use instead of Node's EADDRINUSE text; a listening PHP Remote Debug session shows "Listening for Xdebug on port N" instead of "Running…"; clearing the only field of a debug-only remote type keeps the form and shows the field as required; php-debug leaves the generic Debug adapter list until it has a launch template (#1623).
